In the shipment of fairly heavy commodities in paper boxes, considerablestress at the corners of the box occurs which frequently results inbreakage of the box at such localities. Furthermore considerable weightis frequently placed upon the closure for such boxes. The presentinvention provides a box which may be constructed with reinforcedcorners and with a top of double thickness whereby suflicient rigidityand strength is procured and whereby these disadvantages are greatlyovercome.

The box shown in Fig. 1 comprises a body 10 having side walls 11 and 12and end walls 14 and 15, said body being open at the top and bottomthereof.. The body 10 may be constructed of -a single blank indicated at16 in Fig. 5 which is scored along two parallel lines 1'7 and 18 andalong a number of transverse lines 19, 20, 21 and 22 to divide the boxinto various sections forming the end walls 14 and 15 and the side walls12 and 11, previously referred to and a flap 26 at the end of wall 14.The marginal portions of the blank 16 are formed with V-shaped cuts 23along the edges thereof at the score marks 20, 21 and 22 and withbeveled cuts 24 and 25 at the ends of said marginal portions, whichdivide the same into a number of flaps 27, 28, 29 and 30.

In the construction of the body 10 of the box, the blank is folded alongthe various score marks 19, 20, 21 and 22 and the walls of the boxsecured together through the flap 26 which may be stapled, glued orotherwise attached to the adjoining wall 11. After the walls have beenfastened together the flaps 27, 28, 29 and 30 in both the upper andlower ends of the box may be folded inwardly as shown in Fig. 2 to liein the planes of the top and bottom of the box. Due to the shape of thecuts 24 and 25, said flaps become mitered along the comers thereof whenso folded.

The body 10 of the box is provided with an upper closure 31 and a lowerclosure 32 adapted to close the open portions of the box. These closuresbeing identical in construction, only the closure 31 will be describedin detail.

The closure 31, as best shown in Fig. 3, comprises a cover 33 and a top34 secured thereto. The cover 33 is of a size such that the same maysnugly fit within the walls 11, 12, 14 and 15 of the body of the box andis constructed with flanges 35 and 36 along the edges thereof, adaptedto be bent at right angles to the cover 33. These flanges lie within thebody of the box, when the closure is properly applied thereto, andbeneath the various flaps 27, 28, 29 and 30 of the box proper. The top34 of closure 31 is scored along two parallel lines 37 and 38 which areparallel to the edges of said top and which are spaced a distancetherefrom equal to or slightly greater than the width of the flaps 28and 30. A similar score mark 39 parallel to another edge of the box andspaced a distance therefrom corresponding to the width of the flap 27extends completely across the top 34 and intersects the score marks 37and 38. By means of these score marks, the top 34 is formed with threetabs 40, 41, and 42 which are individually foldable out of the plane ofsaid box for a purpose to be presently more fully described. The top 34is stapled as designated at 43 or glued or otherwise secured to thecover 33 inwardly of the score marks 37, 38 and 39 and at the unscorededge of the box, a distance inwardly therefrom equal to or greater thanthe width of the flap 29, to leave the tabs 40, 41, and 42 and a similarunscored portion 44 at oneend of the closure free from the cover 33.

In the application of the top 31 to the body 10 of the box, thefollowing procedure is adopted.

All of the flaps 27, 28, 29 and 30 of the body 10 are raised from theposition shown in Fig. 2 and the flap 29 inserted into the space betweenthe unscored portion 44 of the top 34 and the cover 33 which I haveindicated at 45 in Fig. 4. The various flanges 35 and 36 of the cover 33are then folded inwardly as shown in Fig. 3 and the entire closure swungon the flap 29 through the score mark 17 thereof, to bring the flanges35 and 36 within the flaps 28, 27 and 30 and within the interior of thebox. When the closure approaches closing position, flap 41 is bentoutwardly along score mark 39 as shown in Figs. 3 and 4. As the closureis brought in place and the flange 35 thereof passes the flange 27 thelatter named flange is folded over the cover 33 to cause the same to liein the plane of the top 34. The tab 41 is then folded down flat upon theflap 27 to hold said flap in place. Both of the tabs 40 and 42 are nextswung outwardly along the score marks 38 and 37 as hinges. Such swingingof the tabs 40 and 42 holds the tab 41 in proper position and while tabs40 and 42 are so swung the flaps 28 and 30 are inserted between saidtabs and the cover 33 and said tabs brought back into the plane of theclosure. After all of the flaps 27, 28, 29 and 30 become lodged inbetween cover 33 and top 34, the box may be bound by cord or metalstraps as is now customary practice which holds the various partsrigidly secured together.

The box constructed as disclosed and with the closure applied thereto inthe manner prescribed, forms an extremely rigid construction. From aninspection of Fig. 4, it will be noted that the corners of the box atthe upper and lower portions of the body all have double thickness ofmaterial and also that the closures of the box are of double thicknessthereby greatly reinforcing and stiffening the box so that the same willstand greater abuse than would be possible where a single thickness ofmaterial was employed. The closure, after the strap or cords have beenremoved, may be readily detached and reapplied as frequently as desireduntil the contents of the box have been consumed. The flaps formed onthe body of the box are completely concealed and the edges of the bodyprotected through the closure of the box, so that considerableprotection is afforded the body of the box from the weight of othersubstances which may come in contact with the bottom closure of the boxwhen the box is in use. Inasmuch as the closures are both removable andinterchangeable, other 010- sures may be substituted in place of thosewhich may become damaged and the body of the box used over again.

The form of the invention shown in Figs. 6 to 10 differs from that shownin Figs. 1 to 6 principally in that a box with an integrally constructedbottom is shown as compared with the other form of box which is open atboth the top and bottom. The body of this box is designated at 78 and isconstructed from a blank indicated at 46 and illustrated in Fig. 10.This blank is scored along four longitudinal lines 47, 48, 49 and 50 andalong two transverse lines 51 and 52 which intersect one another asshown. The score lines 47 and 50 are spaced from the edges of the box adistance equal to the width of the flaps to be formed thereon while theother score lines are spaced so as to give the desired height to theside walls and width to the bottom of the box. The blank 46 isconstructed with four V-shaped cuts 53, 54, 55 and 56, which extendinwardly from the side edges of the blank at the score marks 51 and 52and which extend up to the score marks 47 and 50.

In additionto these cuts, the blank is further severed along lines 57,58, 59 and 60 which coincide with the score lines 48 and 49 and whichextend from the and edges of the blank up to the score marks 51 and 52.By means of the various score marks and cuts, the box is divided to forma bottom 61, two sides 62 and 63, complemental end sections 64, 65, and66 situated at one end of the box, and corresponding end sections 67, 68and 69 situated at the other end of the box. The various parts of thebox may be folded along the various score lines above mentioned and theend sections folded into overlapping position and secured together totake the form shown in Fig. 7. By means of the score lines 47 and 50 andthe cuts 53, 54, 55 and 56, the upper portion of the body of the box isprovided with flaps 70 and 71, adapted to be folded inwardly from thesides 62 and 63 of the box and to form flaps 72 and 73 adapted to befolded inwardly from the ends of the box in the plane of the flaps and'71. The flaps 72 and 73 are formed with sections designated at 74, 75,76 and '7'? of which the sections '76 and 77 lie in continuation of oneanother and the sections 74 and '75 also lie in continuation of oneanother. When these various flaps are folded, as shown in Fig. 7, thecorners thereof become mitered and all of said flaps and flap sectionslie in a common plane.

In conjunction with the body '78 of the box, a, closure 79 is employedwhich is shown in detail in Fig. 8. This closure comprises a cover 80and a top 81 overlying the same similar to the closure 31. The top 79 isthe same as in the other form of the invention, while the cover 80 is ofthe same length as the box but is of a width equal to the distancebetween the two flaps 70 and 71 when the same are folded inwardly asshown in Fig. '7. It is to be further noted that no flanges are formedon the cover 80. By the construction of the closure 79 as specified,only one score mark 82 is required on the top 81 which provides asingle' tab 83 along one of the ends of the closure.

The application of the closure '79 to the box 78 is quite similar tothat described in conjunction with the other form of the invention. Inthis case however, flaps '70 and '71 need not be turned upwardly and itonly becomes necessary to raise and fold the flap 83 in order to attachthe closure to the body of the box proper. When the closure has beenproperly applied to the box, the box is bound with cord or metal bandsas described .with the other form of the invention.

In the form of the invention shown in Figs. 6 to 10 inclusive, anextremely simple and inexpensive box is provided which is exceptionallyrigid considering the amount of material employed in the same. Theclosure for the box may be removed and applied as required and beingconstructed of double thickness is sufiiciently strong to permit ofstacking of the boxes and piling of other articles upon the closure. Theclosure of this form of box is somewhat easier to apply than that of theother form of the invention though less support is had for the closurealong two of as herein disclosed, may be made within the.

scope of what is claimed without departing from the spirit of myinvention.
